Question

a block of mass 2kg rests on the floor.the coefficient of static friction is 0.4.What is force of friction between the block and the floor when a horizontal force P of (1)2 newton (2)8 newton is applied(g=10 m/s^2)

Answer 1

why r u using maths group for physics ?????????????????

Answer 2

no one ther in physics

Answer 3

ohhhh

Answer 4

is ur question correct?????????

Answer 5

yes

Answer 6

f=un=0.4*normal force=0.2kg*9,8*0.4n=7.84nN=7.84N UP.
